Hi

I made a new connection from a 414-3 PN/DP to another 414-3 PN/DP.

The passive 414-3 PN/DP makes an internal error and all led’s flashes, when I activate the communication on the active 414-3 PN/DP.

In Using TSEND FB63, TRCV FB66, TDISCON FB65 and TCON FB64over Ethernet to make the connection.
The passive 414-3 PN/DP has 22 existing connections. And 40% of CPU time is set to communication.

Can anyone tell me why this error occurs or what to do to make the connection to work?
